How to get a TDMS channel datatype programmatically?

[11lora]

Hello everyone,

So I’ve encountered this problem and I don’t know how to solve it.

I’m trying to open a TDMS without knowing what’s inside. I can obtain the Groups and Channels but I have no idea how to get the data type of each channel programmatically.

Does someone know how to do this?

Digging into the TDMS viewer source, it looks like you can use Get Properties API like below to get the Data Type

The following VIs seem to handle formatting the different data types into string

It sure looks like this same question was asked over on Reddit recently.

Yes that's more or less what I told OP to do, but they didn't seem to understand what I suggested.
